I'm having a difficult time believing the story to be honest. Through luck and coincidence I've managed to stay at some pretty nice places around the globe and when you get into a certain level of hotel, you aren't rubbing shoulders with the "let's steal the mattress" crowd. People staying in 5* hotels probably have a relatively nice mattress at home already.

Pro-tip: good luck lifting a Hastens mattress with less than four strong guys under 40, it's not gonna happen.
